On Saturday, July 19, the magnetic storm on Earth will be very weak. The forecast shows that significant geomagnetic disturbances are not expected until at least July 20. This is reported by the Meteoagent service, referring to the forecasts of NOAA and Geomagnetism.
According to the assessment of the US National Oceanic and Atmospheric Administration (NOAA), there are complex active regions in the western hemisphere of the Sun that could potentially cause solar flares. However, the probability of a solar radiation storm of even the minimum level of S1 remains low.
The Geomagnetism portal also confirms that geomagnetic activity will be calm over the coming weekend, with only minor short-term fluctuations.
Magnetic storms occur when charged particles ejected during solar flares reach Earth and interact with the magnetosphere. This most often occurs 1–3 days after activity on the Sun.
The consequences of storms can be felt not only by technology, but also by people:
-
weather-sensitive people experience increased headaches, disturbed sleep, increased blood pressure, and anxiety;
-
possible failures in GPS, satellite communications, and radio communications;
-
auroras appear in high latitudes;
-
Sometimes power system outages are recorded.
The strength of magnetic storms is measured by the K-index. The higher its value, the more powerful the impact on the human body and technology.
However, there is currently no reason for alarm - the current forecast remains within the range of weak activity.
